Stop trading before you breach, not after.
78.7% of failed prop challenges die from the daily loss limit — not from bad strategies. The Prop Firm Shield enforces your daily loss, max drawdown and profit target inside the EA, so a bad cluster of signals ends the day instead of ending the challenge.
Three guardrails, one seatbelt
You configure the numbers from your firm’s rules; the EA enforces them locally, on every signal, even between polls.
Daily loss limit
Set the maximum daily loss as a percentage. When the day’s losses reach it, the EA stops opening trades — the day ends instead of the challenge.
Max equity drawdown
A hard ceiling on overall drawdown, monitored in real time. The guardrail most traders only discover after the firm applies it.
Profit target lock
Set a daily profit target: once the day’s closed profit reaches it, the EA stops trading. A strong day cannot be given back in the same session.
Why “I’ll watch it” doesn’t work
Automated size, automated speed
An EA can stack more exposure in thirty seconds than you would in an hour. By the time you see it in the app, the daily limit is gone. The Shield reacts on every signal, before the order is placed.
The end-of-challenge trap
Most breaches happen near the profit target, when traders oversize to finish faster. The profit target lock removes that temptation mechanically.
Attacks, spikes and gaps
NFP prints and broker spikes do not wait for you. The Shield works with the news filter so high-impact windows are simply not traded.

The Prop Firm Shield reduces but cannot eliminate the risk of breaching prop firm rules; it is not a guarantee and nothing on this page is financial advice. Always verify the exact rules of your firm (daily loss definition, balance vs equity drawdown, news restrictions) and configure the Shield accordingly.
